Object state in Zenoh

[smnrgrs]

Hi, is there a way to mark published Zenoh data as invalid/deleted/disposed so that subscribers know that it is no longer valid or no longer exists?

Hi @smnrgrs, you can use the delete method: https://docs.rs/zenoh/latest/zenoh/prelude/sync/struct.Session.html#method.delete passing a key expression.
The subscribers will receive a Sample with kind delete: https://docs.rs/zenoh/latest/zenoh/prelude/enum.SampleKind.html
